Lignin-derived carbon aerogels (CAs) with hierarchically porous morphologies are facially prepared via ultrafast freezing of droplets of lignin/KOH solutions followed by freeze-drying and in situ activation during carbonization. The CAs exhibit a high specific surface area of 1681.6 m² g⁻¹ and abund...
